## Human Summary
Cloudflare's API Model Context Protocol (MCP) server now exposes Workers Issues as push-based MCP Events.

## Agent Summary
Cloudflare API MCP server now supports webhook-based MCP Events for error monitoring via the 'cloudflare.alert.workers observability real time issue' event. Agents can discover and subscribe to issues per account or Worker, eliminating the need for polling.

## Body
The Cloudflare API MCP server has added support for MCP Events, starting with notifications from Workers Issues, Cloudflare's built-in error monitoring tool. MCP clients can discover the event 'cloudflare.alert.workers observability real time issue' via events/list and subscribe via events/subscribe , with scopes configurable to an entire account or a specific Worker. Once subscribed, the server delivers signed event payloads to client webhooks upon detection of new or recurring issues, enabling agents to act automatically without polling.

## Recommended actions
- Enable Workers Issues on target Cloudflare Workers.
- Connect the MCP server at https://mcp.cloudflare.com/mcp using an MCP client supporting MCP Events webhooks.
- Ensure MCP client credentials include 'Notifications Write' and 'Workers Observability Write' permissions.
- Discover available events using events/list and subscribe using events/subscribe .
